OIL BURNER.

Application mea January 30,1920. serial No. 355,162.

T 0 all whom t may concern: l

Be it known that I, THOMAS H. Pinnen, a citizen of the United States, and resident of Edgewood, city of Cranston, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Oil Burners, of which the following is a specification.

This invention relates to hydrocarbon burning apparatus more particularlyadapt- Ved for burning the heavier oils; andthe object of this invention is to provide an efficient apparatus by which the maximum heat may be generated from the minimum amount of fuel.

A further object of the invention is to provide a centrifugal' burner and means' whereby the surplus fuel about the burner is entirely confined and not exposed to the possibility of becoming ignited, the oil being supplied only as fast as it is consumed.I

A still further object of the invention is to automatically shut off the supply of oil when the burner ceases to operate.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more. fully described, and particularly pointed outin the appended claims. f

In the accompanying drawings:

Figure l-is a sectional side elevation illustrating parts of one operative embodiment of my invention.

F igurelO-is a sectional elevation of the parts shown in Figure9.

Figure ll-is a side elevation of the atomizer member.

With reference to the drawings, l5 designates the base of my improved burner on which the operating parts are supported. In this base I have `constructed a plurality of air-inlet passagewaysl which are controlled by adamper 17 moved by a rod 18 whereby the opening through these passageways may be nicely controlled to. limit the amount of air that shall be permitted to pass to the burner.

On this base I have mounted the casing 19 which is preferably formed hollow provi/l ing 'la central oil-carrying chamber 20, the

, contents'of which serve a double purpose whichis that of lubricating the operating parts and also'keeping the casing comparatively cool. On the upper side of this chamber I have mounted ka centrifugal atomizing member 21v which may be constructed in any suitable way, the preferred form, however, being illustrated lin Figures 9 and 10, in which a distributinfrdisk 22 is provided with a sharp, circular e ge 23 having an inclined under surface 24up which theoil which enters through the openings 25 passes to be thrown from said edge 23.

A second disk 26, larger in diameter than disk 21, is provided with a distributing edge 27 on a pla-ne lower than edge 23 and this disk 26 is provided with radially-disposed channelways 28 in its face leading from the oil feed-holes 25 to the distributing edge 27 The under side of this disk 26 is also provided with an upwardly-inclined surface 29, which is supplied with oil vdeposited on the under side of this disk 21 by the feedermember, presently described.

This lower, inclined surface also terminates in a sharp, oil-distributing edge 3l which is of greater diameter than the distributing edge 27 and is on a plane lower than said edge 27.

The` outer periphery of the disk 26 between the edges 27 and 31 is so shaped that the oil will be thrown from edge 27 and will not travel down to edge 31.

By this construction of atomizer it will be noted that the fuel is being distributed simultaneously frni'l these dihlent fevels and from circular edges of these dierent diameters. 4 ,Y u '5 This centrifugal atomizing memberA is mounted on the upright sha t 32, oritlll lower end of which shaft is mounted a gear 33 which meshes-y with gear 84,on the driving shaft 37 from which this shaft-and atomirer are rotated at a high vlit'y.

In orderto nicely control, the. $119913l 0f oil tI this'gm 'tifiugal memberl have proy a 'fee' er-niemb preferab1 in di lomwhicli is mounted on thediiying .sha t 37 to 'rotate in a plane ata right angle to that .of the atomizihg meu ber. vIn this feeder have shown a pluia it rad'al ducts or passageways 38 leading romy t e center thereof to its periphery this being shown as tbeing lsupplied throughvthe hollow driving-'shaft 37 but which may be supplied thereto b any other Psuitable means.

This s aft is shown as being provided with a gear 41 which transmits mo ion thioiigh the belt 42 to Y'a pump 44, which pump 'receives the oil from, any suitable source of supply and conducts the same through a tube around through the c oil 46 wh'ch is preferably placed in," roxlmlty vto, the cated parts whereby the oifis heated 'prviens toits being conducted bacli'thron the pipe t the chamberkis iawhichtj' agitator 9 operates. vThis agitator is for tre' rpose of working lthe oil over and over sm'ooth out hard substances and place the oil inv condition to vflow more uniformly,

and fee'l through the conductors.

From t is' itator c'hamberathe oil is conducted thro the tubular shaft 37 to the axis of the feeder-member;

It foind in practice owing to varying atn'os 'herie temperatures that the heat require is not always uniformv land, 'therefore the sup y of fuel must vary andas I have provides` means for regulatinlg the supply which in this case is Vaccomp ished by the provision of a bypass or return pipe 50 which is connected at one end to the main supply at 'a fpoint adjacent the feeder-member and yleads back to the intake side ofthe pump. This bypass is provided with a control valve 51 which ma be adjusted by hand or by other means (lnot shown) to control and determine the amonntof fuel which shall be conducted to the. feeder-ine ber.

It will be noted that the `eeder-member is so geared that its surface will run in ya direction opposite 'to the adjacent surfaceof the atomizing member 26', the openings 25 in this vatomiaing member being spaced to. register with the radiating passageways 38 in the feeder-member at certain intervals so as to pass oil intermittently through holes 25 in.

to the lupper Asurface The feeder-member is also arranged to distribute a 'certain amount of oil oh theunder surface of the centrifugal plate, whlch oil due to centrifugal force acting upon 1t 1n the radial feeder-passageways, works outwardly *and radially on the bottom of the atomizing plates past the flow-restricting and heatresisting packing ring 52, to be conducted thro h the passagewa s 30, see Figure 11, and lisch'arged from t e lower edge 31 of the centrifugal atomizer.

' In order to shut olf the flowv to this feeder member automatically, when not needed, I have provided a ball valve 63adapted to be pressedlightly by spring 64 agai the oenterv intakeY whereby the suction on te oil due to centrifugal force, caused by the rapidly rotating feeder, will cause the valve to open and rmit a. further su ply and as soon as the eeder' ceases to ro ate, this valve will close and shut oil' the supply thereby reventit waste and dan crous overflow o oil.

nuie lower side o this atomizi member I 'have secured` a plate 53, the ace of which is provided with a plurality of scoopshaped depressions 54 whlch are adapted to collect the air in rotating rapidly to direct it-at an angle upwardly to supply oxygen to., e'flame.

` Vhe outeredgeof thisl plate 53 is slit as :1h55 at 4closeA intervals, one edge of which isv turned dwnwardly and the other upwardly to provide a Afan-shaped member lfor further drawing the air upwardly 'throu h the air passageway v56,111 the casing and irecting it against the fuel in 'sus nsion to tu i1 the same in yan u 1ward directlon.

t will be noted hat the fuel is being atouzed and thrown out radi lly with considerable forceV from three diherent planes whicheffect wouldbe to have ablaze in three separate, horizontal planes, and the fu ction of this fan or blower is'to provide s cient draft to supply oxygen for combustion and also Vturn the different strata of the flame upwardly causing an intimate intermingling of the atoms in us ension and controlling the a le at whicli t e llame isvprojected. i

As tiis blaze and the heated gases t erefrom are forced outwardly and upwar y, a central, downwardly-directed current of heated gases is na urally created, which downward flow serves to heat the upper ring or plate 57 to incandescence and so further advthe combustion of the oil which is bein thrown off from the upper edge 23 as'some o vthese gases after coming in Contact with the into ,thezone of combustion, I have provided a saucer-shaped structureon the casing, the same being provided with a bottom plate 60, the outer-edge portionl of which is turned upward on an incline as at 61, which structure in addition to its heat-confining function is also found to be useful in pro-V` tecting the fan blades see Figure 10 and supporting the fire box protector lining also serving as ameans for collecting unburned fuel.

In order to provide means for maintainincr the centrifugal atomizing parts at a su cient temperature for immediate combustion when supplied with oil, also for igniting the oil when supplied I have provided a series of so-called pilot lights which are preferably located beneath and are arranged to act upon the lower surface of the atomizing parts.

The means for providing these pilot lights may be constructed in any suitable form but I have herein shown a pipe or tube 61 bent into a plurality of loops 62 to fit into the air passageways 56,1each loop being provided with an opening 63 from which the flame burns, which flame is supported by a suitable fuel which may be either gas or oil supplied through the pipe 64 or the same may be heated my electrical coils (not shown).

The foregoing description is directed solely towards the 'construction illustrated, but I desire it to be understood that I re serve the privilege of resorting to all the mechanical changes to which the device is sus ceptible. the invention being defined and limited only by the terms of the appended claims.
